JIMS has released a line of race engines beginning with the 131ci Twin Cam race engine.

The 131ci, which fits into all stock and after market frames, features a 4- 1⁄2 stroke with a bore diameter of 4-5⁄16in. The CNC-ported heads were developed specifically to flow maximum air, and the oil pump is upgraded from the stock H-D unit. A billet cam support plate, which utilizes Harley-Davidson’s new hydraulic cam chain tensioner, is fitted as are the new JIMS Powerglide II hydraulic tappets.

The engines fit Twin Cam Touring and Dyna models, as well as the ‘91-’99 Evolution model.
An additional version of the 131ci motor has been developed which will bolt directly into Evolution style frames of older H-D models.

The range of 131ci engines is complemented by a 120ci Twin Cam race engine for 2000 - 2006 Softail models. The JIMS 120ci is the only race engine available for counter-balanced Softail models. It is claimed to deliver 121hp and 125 ft-lbs of torque.

JIMS thick-walled cases offer greater strength and can support a bore size of up to 4.800. This engine features pressed flywheels, forged pistons, Screamin’ Eagle valve springs, forged 4340 steel connecting rods and the latest JIMS Powerglide II tappets.

As with the 131ci version Jims offers a 120ci Twin Cam engine which will bolt into a frame designed for an Evo.
